1. SAFETY PRECAUTIONS
SA221/324/424 Operation Manual
On a slope, the tractor is less stable and more prone
to tip over, possibly leading to serious injury or death.
Remain very cautious while the tractor is on any
slope.
DO:
●Operate up and down slopes, not across.
●Remove obstacles such as rocks, limbs, etc.
●Watch for potholes, ruts or bumps. Uneven terrai
n
ca
n overturn the tractor. Tall grass can hide such
obstacles.
●Place the transmission in the low range wh
en
clim
bing or descending slopes. Always keep th
e
tr
actor in gear when going down slopes to
take
advan
tage of engine braking action.
●Keep all movement on the slopes slow an
d
gr
adual. Do not make sudden changes in speed
or
dir
ection. Rapid engagement or braking can ca
use
th
e front of the tractor to lift and rapidly tip over
backwards which can cause serious injury.
●Avoid starting or stopping on a slope. If ti
res lose
t
raction, push down Power Take Off (PTO) switch
to OFF position and proceed slowly straight down
the slope.
●To avoid tipping or turn over, move backward up a
steep slope. If backing on the slope is difficult, do
not attempt to continue. Avoid an extremely stee
p
slo
pe.
●When moving forward to get out from a ditch, deep
mud or when traveling on a steep slope, th
e risk of
th
e tractor tipping or turn over backward is high
.
Al
ways move backward to get out from th
ese
s
ituations. In the 4-wheel drive mode, spec
ial
ca
ution is needed to avoid potential tipover when
traveling up and down slope site conditions.
●To improve stability on a slope, select the wides
t
possible
tire tread width. Observe the instru
ctions
fo
r appropriate weighting.
●Do not operate on wet grass. Tires may lose
traction on slopes even though the brakes are
functioning properly.
●Keep away from drop-offs, ditches or
embankments during mowing. The mower could
suddenly turn over if a wheel goes over the edge of
a cliff, ditch or if an edge caves in.
5. Operate the Tractor on Slopes
●Keep away from slopes steeper than 15
degrees. See page 8-17 "Operate on Slopes
and Rough Terrain" for the details.
●Before approaching a slope, select an
appropriate speed setting. Make sure to
run
t
he tractor at a lower speed on slopes. Never
attempt to shift gears on a slope. The tracto
r
c
an suddenly go downhill out of cont
rol.
Avo
id increasing and decreasing the tractor
speed rapidly.
●Do not move the range shift lever in the
N
(
neutral) position when on a slope.
●When climbing or descending a slope, do not
shift the range shift lever. Shifting the range
shift lever into the N (neutral) position ca
n
r
esult in loss of control of the tractor.
●Starting the tractor with the front end uph
ill
c
an cause the front wheels to jump off th
e
g
round and this situation poses an extreme
danger. To avoid this problem, run the engine
at a lower speed, and gently start the tractor.
●Avoid parking the tractor on a slope. If parkin
g
o
n a slope is unavoidable, chock all the tire
s
s
afely and securely and engage the park
ing
b
rake securely, for details, see "6. Lock and
Set the Parking Brake" on page 7-3.
